Most spiders are primarily active at night, which means they are nocturnal. However, some spider species are diurnal, which means that they will be at their most active during the day.
Spiders don’t have good eyesight. So, for getting around during the night, spiders will not use their eyesight. They will use other senses such as identifying vibrations using their body hair, which allows them to sense animals and the environment around them and gives them a strategic advantage.
Are Spiders Nocturnal?
Some spiders are nocturnal, while others are diurnal. Some spiders are fully nocturnal, which means that they will rest during the day and hunt at night; others might be active both at night and during the day.
Most spider species prefer to stay active at night because they rely on senses that allow them to stay hidden and hunt successfully during this time of day.
At night, they’re also more protected from predators.
Nocturnal spiders will rely on vibrations and touch to get around. Many of these have sensitive hairs on their legs and abdomen, which allow them to feel their surroundings and get a better idea of where other animals are.
Insects that spiders hunt are also active at night. Therefore, there is a natural benefit to night activity: they will be able to catch their target prey!
Are There Diurnal Spiders?
Even though the majority of spiders are active at night, some spiders remain at their most active during the day. Research shows that some species have moved from being nocturnal to being fully diurnal throughout their evolution.
Researchers have found that this happened because of the UV rays and their effect on spiders and their silk. It’s said that UV rays have affected the capability of spider webs to capture prey, and they might be more effective during the day because of the irradiation caused by the sunlight.
Spiders that Come Out at Night
The majority of spiders are nocturnal, which means they come out at night. These are some of the most common and well-known spiders that come out at night.
1. Orb-Weaving Spiders
Orb-weaving spiders are very active during the night. These spiders are known for their capacity to create orb-like webs, which are very effective for capturing all types of prey – primarily insects.
These arachnids will construct their webs at dusk, ready for a night of waiting in the middle of their webs to catch their prey. At dawn, many of them deconstruct their webs and wait in hiding until dusk comes around again.
Tarantulas are hunting spiders, and they will do most of their hunting at night. They will travel around their habitat in the dark, looking for opportunities to strike. They prefer ambushing as a hunting technique.
When they’re not hunting, tarantulas will work on their burrows at night, breed, and do other activities that allow them to survive. If you happen to own a tarantula, you’ll see that it’s most likely to move around at night.
3. Black Widows
Black widows are some of the most feared spiders in the world, and they will do most of their activities at night.
They’re also hunting spiders, so most of their hunting activity will be conducted at night. The black widow has a potent venom, allowing it to go after even larger animals of prey.
4. Brown Recluses
The brown recluse is also a feared spider species. They tend to come out at night, while also spending the majority of their days in hiding.
That’s why they’re called recluse spiders – they will rarely come out during the day, so you might not be able to see it at all.
The brown recluse is a very prominent hunter. It relies on its instincts and of course, its potent venom. This allows it to capture large amounts of prey in a short space of time during the night.
5. Wolf Spiders
The wolf spider is perhaps the most well-known hunting spider species that comes at night. So far, we’ve seen that many spiders that come out at night are hunting spiders, and the wolf spider is no exception.
This species is known for its relentless hunting style and fine-tuned senses that allow it to capture a lot of food at night. Sometimes, this spider is also spotted during the day, but it is much more common to find it outside at night.
Wolf spiders have a special reflective grate behind their eyes which helps them see at night. This often gives them the appearance of having glow-in-the-dark eyes.

6. Common House Spiders
Common house spiders are also more active at night. They will primarily hunt at night and do other activities while making sure that they stay out of sight during the day.
The common house spider is also a pretty good hunter. It is known for its appetite for insects, so most of its hunting will be shaped around its ability to catch insects in its habitat.
Do Spiders Sleep During the Day?
Most spider species will sleep or rest during the day, either in the comfort of its web or its burrow.
Nocturnal spiders are more active at night, while during the day, they will spend most of their time resting. They can consume a lot of energy when hunting at night, so they will want to replenish that energy during the day as much as possible.
They like to hide in cooler areas where they have a lot of protection, such as rocks, cavities, and burrows. They’ll create nests in these areas and possibly webs if they are a species that likes to create webs.
They still need to keep a watchful eye at night, because other animals might be lurking to find food and maybe even capture the spiders as they are sleeping.

Most spider species are nocturnal. They will spend most of their time at night hunting, which they will do using their strong senses of vibration and touch. They don’t have very good eyesight though, but that’s not a hindrance for most nocturnal spiders. During the day, nocturnal spiders rest up and prepare themselves for the next busy night of hunting. Among the most common nocturnal species are tarantulas, wolf spiders, black widows, brown recluses, and common house spiders.
